Serial No. 444,9304 cl ims. (01. 271-44)- 'My invention relates to improvements in paperstrip dispensers, andmoreparticularly, has referencegto and isillustrated in the accompanying, drawing in, its application to-a gummedor 4 adhesive paper strip dispenser device, such as is, adaptableforiclosingpaper packages and the like, andis an improvement on thedispenser disclosedin my co-pending patent application S. N. 396,999. V

Referring to the accompanying drawing, Fig. 1.illustrates inperspective,parts being broken away, a part of-a disriensingmachineshOwing anembodiment of my invention. .Fig. 2 is an enlarged. longitudinalsectional detail illustrating parts mounted upon the shaft. Fig. 3illustrates part of the paper feed mechanism, partly in section, andparts broken away. Fig. 4 is a detail in perspective illustrating partof the strip forming and guiding mechanism. Fig. 5 illustrates, partlyin section and'parts broken away, part of the finger control foroperating the device. Fig. 6 is a View looking from right to left atFig. 5, and Fig. 7 is a sectional detail of the water box and brushmoistener mechanism.

8 indicates the frame of the machine, having a circular frame-likeportion 9,. projectedlaterally therefrom, with a series of holes 10, forengagement by the pin 11, in the lever 12 for predetermining thelengthof gummed strip to be torn off. Through the center of the frame isprojected the spindle714, having rotatably mounted thereon at the outerend, .a lever 15, said lever having a counter weight 17, and beingconnected at the-top with another lever 18, by a pin 19, which pivotallyretains the finger portion 20, for dispensing the strip.

The finger portion 20, pivotally mounted at 19, upon the two arms 15,18, is provided with a deportion 24, that prevents rebound leftwardlyofr the lever 15, after it hasstruck the stop. This stop 23 is part of, orsecured to the lever 12, which is mounted on the spindle 14,- as shownin Fig. 2, and which is preferably made of resilient material to permitthe end 12 to be pulled ,serving as a, bearing forqthe lever 12, and forpending portion 21, which whenthe finger portoward you while shiftingthesame around the ring 9 for changing engagement of the pin 11,with'the' holes '10 therein, thus shifting the stop 23, at anydesiredpoint around (the circle and thereby varying the swing or strokeof the finger piece and lever 20, 15 respectively. 24' serves as anindicator or pointer, if desired, for indieating the lengthof strip tobe cut.

Upon the shaft 141-issecure d ahous ing 25,"at

the right end of which is a reduced' portion '26 seating in the frame,8. This housing is preferably secured to the frame 8 at three pointswith screws 27, and. has an internal circular chamber 28, withinwhichmay be lsecured the coiled flat spring 29 at one end, as indicatedat- 30, the opposite end being secured at 31, to an oiT-set 32 from the1ever'18, and at the'outer end of the shaft 14, is provided the ring 32,penetrated by the pin 16, for holding the combination referred to inproper relation upon the shaft 14; from all of which,,it' will be seenthat by pulling the finger end 12' of the lever 12. toward the operator,the 'saidlever12 may be moved to the right or left, thus increasing orsea decreasing respectively, the sweep of the lever :89 7

The free end 35 of the strip after passing between the rollers 33, 34,is raisedin the center by the tapered elevation piece 36, shown to ad-;vantage in Fig. 4, thereby slightly channeling and stiffening the stripto insure proper rigidity of thestrip forfeedingofthe sameleftwardly,7100 the cutting-01f mechanism'being preferably substan'tially'as shownin my co-pending case re-,-

The water-box for moistening the gummed stripbeneath, as it feeds out ofthe machine, is shown to advantage in Fig. '7, wherethe water level-ispreferably as indicated' at 37, the bristles 38, of the brushextendingupwardly to contact with the under gummed surface of thestrip,

the brush is backed by an inwardly projecting portion 39 of the Waterchamber 40, and is preferably at the base, with a metallic holder 41,

I for the'bristles, and projecting inwardly from the bottom of thechamber 4!}, is preferably provided a tongue or tongues 42, which snapthe top edge of the metallic holder 41, thus hold ing the sameproperlyseated upon the base 43, and when it is required. to remove thebrush, the bristles 38 are pressed back against the springlike support39, thus moving the holder 41 free from engagement with the prongs 42,allowing the brush to be pulled upwardly and withdrawn.

Of course, it will be understood that various combination with saidlever, a disc and means connected therewith: for feeding said stripwhereby when said finger piece is operated and said 'levermoved, saiddisc is rotated, and an adjustable stop for controlling the length ofthrow of said lever. 2. In a strip feeding mechanism; a casing, asupport therein for a strip of material to be fed, feed rollersengageable with the strips for feeding the strip from the machine, aspindle, an arm Ireely movable about said spindle as "and member in onedirection, operative connections between the spindle and strip feedingmeans, spring means for rotating the arm in one direction, andadjustable means to limit said 7 an axis, a member fixed to saidspindle, driving connections between said spindle and saidrollers, andpivoted finger engageable means on said arm engageable with the memberfixed torthe spindle when the arm and pivoted means are moved in onedirection.

3. In a machine ofthe character described, a casing, a support thereinfor a strip to be fed, feeding means engageable with the strip to feedsaid strip, a spindle, an arm pivoted for free movement thereon, amember fixed on the spindle, a hand engageable member movably mountedonthe arm and engageable with said memberon the spindle upon movement ofthe arm movement.
